Microbiologically induced corrosion sulfate reducing bacteria in stainless steel AISI 316L

Abstract:

In this article, the behavior of microbiologically induced corrosion is studied by Desulfovibrioaminophilus in AISI 316L stainless steel. Bacterial characterization was conducted by macroscopic and microscopicmorphological and biochemical tests. The growth kinetics is observed through periodicre views; and electrochemical characterization by impedance diagrams and polarization curves Tafel. There cambiar results showed the growth of colonies in the surface material of variable and unstable take aggressive action of generating localized pitting, after the exposure time expolisacaridos matrix is generated, which reduces the corrosion rate in the sample of AISI 316 L.
